<h2><a name="_description"></a>DESCRIPTION <a href="#_top"><img alt="^" border="0" src="../up.png"></a></h2>
<div class="fragment"><pre class="comment"> One-dimensional mode filtering.

 Applies an order 2*r+1 one-dimensional mode filter to vector x.  That is each element of
 the output y(i) corresponds to the mode of x(i-s/2:i+s/2). At boundary regions, y is
 calculated on smaller windows, for example y(1) is calculated over x(1:1+s/2).  Note
 that for this function to make sense x should take on only a number of discrete values.

 INPUTS
   x   - length n vector 
   s   - filter size

 OUTPUTS
   y   - filtered vector x
 
 EXAMPLE
   x=[0, 1, 0, 0, 0, 3, 0, 1, 3, 1, 2, 2, 0, 1]; s=4;
   ymedian = medfilt1( x, s );
   ymode   = modefilt1( x, s );
   [x; ymedian; ymode]
